User Manual
Operation and Management
The IRD-2900 IP front end supports both physical link and logical source
redundancy. The physical link and logical source are coupled, i.e. switching from
one physical link to the other (in the case of a link redundancy event) forces
switching from the corresponding logical source to the other. In the case of a
logical source redundancy event, the physical links are switched as well.
• Link Redundancy: protects the directly connected switch/router and the
physical cable connection. There are two IP physical links to the IRD-2900:
MPEGoIP IN1 and .MPEGoIP IN2.
• Source Redundancy: protects the transport stream source
(encoder/streamer). Two logical sources (i.e. sockets), containing identical
streams, must be configured to enable Source redundancy.
REDUNDANCY EVENT
A redundancy event causes the IRD-2900 to switch from the active Physical Link
and Logical Source to the passive ones.
The device identifies a redundancy event when all the following conditions apply:
• Redundancy mode is enabled
• Active physical link failure (through PHY indication) or active logical source
failure detection (no stream is being received for a preconfigured
Redundancy Delay time [see next page)
• Passive physical link is configured, up, and connected
• Passive logical source is configured and connected
The following menu is used for enabling or disabling the operation of the
redundancy feature.
